19 Claims.

This invention relates to razors and more particularly to safety razors.

One object of the present invention is a razor wherein the blade may bemoved into and out of shaving position without uncovering the cuttingedge. Another object is a razor of the type wherein one or more bladesmay be carried, the blade carrying member being adapted to move the sameblade into and out of shaving position or to be rotated to bring a newblade into shaving position. Another object is a razor of the abovementioned type which may be readily cleaned without exposing the bladethereby eliminating the possibility oi cutting the person clean- 15 ingsame. A still further object is a razor wherein the guards automaticallyclose over the cutting edge of the blade after being opened for cleaningor to receive a new blade. A further object is a razor having asharpening device as 20 a part thereof.

These and other objects will be readily understood from the followingdescription and with references to the accompanying drawing in which:

Fig. 1 shows a perspective view of one embodiment of the razor with theparts in relative position for assembly;

Fig. 2 is a side view partly in section of the razor in assembledposition with the blade in shaving position;

30 Fig. 3 is a side view of the razor with the casing members open andthe blade withdrawn from shaving position;

Figs. Ll, 5 and 6 are diagrammatic views illustrating how the deviceoperates; 35 Fig 7 is a diagrammatic view showing the construction of ablade and its mounting in the blade carrying member; and

Figs. 8 and 8a are front elevation and end views oi' the Sharpenerrespectively.

Referring to the drawing, the razor comprises in general a blade housingl having abottom casing 2 and a top casing t, a blade carrying member d,a recoil spring 8 and an extension member Ill. The bottom casing 2 isprovided 40 with a front plate i2 having the usual toothed projectionsforming the lower blade guard il! common to safety razors. The sideplates iii are provided with vertical slots lil, having a narrow r lowerportion la and wide upper portion i817, and

0 a transverse slot 20 extending forwardly from and at approximatelyright angles to, the slot i8. De-

pending from the bottom of the casing 2 is a hollow handle 22.

The top casing (i consists of a top plate which 55 serves as a top guard28 for the razor blades and from which depend a pair of side plates 2Q,the side plates each being provided with an inclined slot 3l?, andextending downwardly from the rear edge of slot 3@ is the inwardlyprojecting guide and turning lug 32. Depending from plate 28 is 5;` anoperating arm 34.

The blade carrying member l is provided with a rotor 24 groovedl toaccommodate one or more blades, securely carried therein in any suitableway, the ends of the rotor being reduced in size 10vl` to form thebearings 26.

The rotor 2s (Fig. 7) is slightly narrower than the blades, permittingthem to project from the grooves therein to form a series of spacedprojections lill around the end of the rotor equal in T number to theblades carried by same, which projections serve to rotate the rotor whencontacted by projections 32 of top casing ii, as will be hereinafterdescribed.

When assembled (Fig. 2) the blade rotor is 20 supported within housing lby bearings 2t which project through slots 2Q of bottom casing 2 andslots 3i! of top casing t. The operating arm 34 telescopes within handle22 and as top casing 6 1s lowered, lugs 32 enter slots IB. As bearings25 25 project slightly beyond the sides of bottom casing 2 they contactirst with lugs 32 which move them forward a suicient distance to enterslots 30, and upon further downward movement the angular inclination ofslots moves rotor 30 24 forwardly to operative position carrying theblade l til into shaving position between the lower guard lil and topguard 28. Recoil spring 8 is then slipped into handle 22 around theoperating arm 34, and the extension member lil is then placed intohandle 22 and screwed to arm 34 completing the assembly, the tension ofspring 8 maintaining the casing members in closed position. Upon pushingupwardly on member I0, (Fig.- 3) the upward movement of top casing 6 40moves rotor 24 rearwardly, drawing blade |00. from between the guardsout of shaving position but without exposing same. Upon releasing memberIt the compressed recoil spring 8 causes u the parts to close andautomatically return blade lili? to shaving position.

The operation of the razor to move the blade carrying member l into andout of operating position to move a blade into and out of shavingposition or to bring a new blade into shaving position will be readilyunderstood from Figs. 4, 5 and 6.

As casing member 6 is raised, lug 32 is also raised and slot 3i! causesrotor 24 to move rearwardly, the ends of the blades being grooved at V|02 to permit them to pass lug 32 as it moves vertically. VAs therearward motion is rapid, rotor 24 will be carried far enough back tobring lug 32 under one of the blade projections mi (Fig. 5) and, uponfurther upward motion, lug 32 rotates the rotor, bringing blade |000.into po sition to be carried horizontally into shaving position onthedownward return of the top casing 6 (Fig. 6). On the downward motionlug 32 contacts the next projection i!!! but the angle of impact is suchthat it tends to move the rotor forwardly without rotating same.

As illustrated in Figs. 4 to 6, a Sharpener 59 of spring steel or othersuitable material lmay be carried in the top casing 6. The Sharpenercomprises a pair of longitudinally extending jaws 52 and 53 inclined toeach other at an angle of approximately 7 to give a sweeping motion asthe blade is withdrawn therefrom. The jaws are hinged at their ends bythe compound curvature 55 which tends to spring them open and issupported in top casing 6 by the indents 58 and 69. Depending from therear jaw 53 is a hook 54 which projects downwardly into slot I8. Whenthe top casing 5 is in closed position curvature 55 contacts with lug BSon casing 2 which forces it upwardly between indents 58 which compressessame and forces the sharpening jaws tightly against the blade Ima. Ascasing 6 is lifted the Sharpener wipes over the blade until hook 64 andagain receive the blade on the return movement.

As blade Illa, slot 3D and jaws 52 and 53 are all inclined at the sameangle, the blade will readily leave the Sharpener on the rearward motionof the rotor and return on the forward motion or if the next blade |001)has been rotated to the former position of Ilma, it will enter theSharpener on the forward motion.

It is apparent from the foregoing that by the one upward motion of theoperating arm extension ID, the blade liil is withdrawn from shavingposition, the blade |0011, withdrawn from the Sharpener, and the rotor 4turned through a predetermined amount, and that by a downward motion,which preferably is done automatically by spring S, blade I 00a iscarried into shaving position and blade limb into the Sharpener thusrequiring but a single manual operation to bring a new blade intoshaving position. When it is desired only to clean the razor the partsmay be moved to the position shown in Fig. 5 whereupon a stream of watermay pass between the blade and lower guard and through holes 23 inbottom casing 2 and upon releasing the operating arm extension I0, thesame blades will return to the shaving position or enter the Sharpener.

Although the embodiment shown carries iive blades this number may bevaried, and the Sharpener may or may not be included as desired. It willbe noted that at no time after the blade or blades are inserted in thehousing is the cutting edge of any blade left exposed therefrom, exceptwhen held between the guards. The razor is preferably made of a light,stainless and noncorrosive metal, and the blades of stainless steel.

As will be evident to those skilled in the art, the invention permits ofvarious modifications without departing from the spirit thereof or thescope of the appended claims.
